Public Perception of Urban Green Spaces and its Tree Diversity in Delhi

The relationship between man and nature plays an important role in the everyday lives of human societies. Places like Delhi and its people face major challenges and issues of urbanisation affecting their health and well-being. Urban greens such as parks play a major role in bringing greenness into the lives of urban dwellers. Trees are seen as a major green component in the urban greens. This paper attempts to understand how public sees green spaces and their uses. Tree diversity index (The Shannon Index also known as Shannon Weiner Index, is a statistical index that measures diversity by estimating species richness and evenness.) canopy cover, and tree trunk diameter have been taken as indicators of greenness of park. Tree distribution at the species level is studied in one of the parks managed by Delhi Development Authority as ‘Landmark greens’. The park users’ perception is studied using an ethnographic method. Whereas the Shannon index is 2.2, which is a moderate value, 50 per cent of the visitors could only identify the popular species namely Neem, Banyan, Ashok, and Peepal. People are aware of the potential benefits of trees and plants or the role of green spaces in their overall well-being. Some of the visitors are the regular ones as they use the park with a purpose to heal from respiratory tract infection, obesity, diabetes, and palpitation, while there are 22 per cent visitors who found the park unsafe during certain instances.
